20130176000 | BATTERY CHARGING - A method and system for controlling charging of a rechargeable battery to obtain a desired state of battery charge. In one embodiment the method comprises assessing an indicator of state of battery charge to determine current battery charge and determining the desired state of battery charge at a predetermined point in an expected battery load pattern. Then receiving an indication of an operational characteristic of an available charge source per time slot to charge the rechargeable battery until the predetermined point and calculating in which of the time slots to charge the battery in order to charge the rechargeable battery to the desired state of battery charge by the predetermined point in the expected battery load pattern to optimise a charging characteristic to the predetermined point. A device and computer program produce is also disclosed, to run continuously, subject to configured parameters, to optimise charging characteristics. | 07-11-2013 |
